Apartment Building, Residential Rochester, MN – Fire officials credit sprinkler system in extinguishing apartment blaze October 31, 2015 viking210 Officials with the Rochester Fire Department are crediting a “sprinkler save” with extinguishing a fire inside an unoccupied apartment Thursday evening. Firefighters were sent at 5:54 p.m. to 2804 Second St. SW in response to a sprinkler alarm — sent by facilities when the sprinklers have been activated. When they arrived, the apartment was full of smoke, said Deputy Chief Vance Swisher, but the flames had already been extinguished, thanks to the sprinklers. A preliminary investigation indicates a lamp that had been left on fell onto some combustible materials in a children’s bedroom, he said. The ensuing fire activated two sprinkler heads, putting out the fire before it could spread. “It could have been a significantly larger fire,” Swisher said, “and certainly done more damage to the building.” The residents of that apartment were unable to stay there because of the water damage, he said, and the apartment below it may have sustained some damage, too.
